Just for fun I did film some video footage from my 60Hz monitor to see how quickly my terminal starts up. Seems like 2-3 frames to show up the terminal window, and 1-2 frames to show shell prompt. So 50 ms - 83 ms. This is with foot terminal on Sway.<p>My very unscientific methodology was to run<p><pre><code> $ echo hello && foot
</code></pre>
in a terminal and measure the time between the hello text appearing and the new window appearing. Looking at my video, the time from physical key press to "hello" text appearing might be 20ish ms but that is less clear, so about 100 ms total from key press to shell prompt.<p>This is pretty much completely untuned setup, I haven't done any tweaks to improve the figures. Enabling foot server might shave some milliseconds, but tbh I don't feel that's necessary.<p>It'd be fun to do this with better camera, and also with better monitors. Idk how difficult it would be to mod in some LED to keyboard to capture the exact moment the key is activated, just trying to eyeball the key movement is not very precise.
